# 生成随机颜色
def random_color():
    return random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)


# 判断是否碰撞，并使大球吃掉小球(小球消失，大球变大)
def eat(ball1, ball2):
    x1, y1 = ball1['pos']
    x2, y2 = ball2['pos']
    x_distance = x1 - x2
    y_distance = y1 - y2
    distance = math.sqrt(x_distance ** 2 + y_distance ** 2)
    if distance < ball1['r'] + ball2['r']:
        if ball1['r'] > ball2['r']:
            ball1['r'] = ball2['r'] + ball1['r']
            all_balls.remove(ball2)
        else:
            ball2['r'] = ball2['r'] + ball1['r']
